Improvement in cultivators



UNITED STATES PATENT OEEIoE.

FRAN GIS N. WELDEN, OF ROGKFORD, ILLINOIS.

IMPROVEMENT IN CULTIVATO RS.

Specification forming part of Letters Patent N0. l 12,994, dated March21, 1871.

To all whom fit may concern:

Be it known that I, FRANcIs N. WELDEN, of Rockford, in the county ofWinnebago and State of Illinois, have invented new and usefulImprovements in Gult-ivators; and I do hereby declare that thefollowing` is a full and exact description of the same, reference beinghad to the accompanying drawings, and to the letters of reference markedthereon.

This invention relates to that class of cultivators which are providedwith an auxiliary frame carrying the shovels, in connection with themain frame resting upon wheels and consists in certain details ofconstruction, which will be fully described hereinafter.

In the drawings, Figure 1 represents a side elevation of a section of acultivator, showing my improvements. Fig. Z'represents a front elevationot' the same 5 Fig. 3, views ot' the ring connecting the standard to thebrace-rod and Fig. 4, views of the spring-bolt attached to thelifting-lever.

To enable others skilled in the art to make and use my invention, I willnow proceed to describe fully its construction and manner ot operation.

A represents the axle; B, the frame, and O the tongue. These partstogether constitute the main frame proper.

E E represent the shovel-beams, united in front by the iron c, and alsoby the bowed bar c. These beams, connected as described, constitute theauxiliary frame which carries the shovels.

The form of the iron c is peculiar. It is bent in such manner as to formsuitable curves for guiding the stalks of corn in between the beams whenthey are high enough to come in contact with it. Its fro'nt end isattached in any suitable manner to a center at the evener I or back ofit, though I preferably use an eyebolt in connection with thehammer-strap, as is shown in Fig. l.

The standard is secured to the shovel-beam in the ordinary manner. Theconstruction of the ring, however, which connects the standard to thebracelrod is peculiar, being slotted upon its rear side, as is clearlyshown in Fig. 3. Its vertical position upon the standard is secured bymeans of a stay-pin, which is inserted in the slot, as shown in Fig. l.By means of this construction the standard may be adjusted in the ringwithout changing the position of the latter.

F represents a standard formed of a bent bar, which is securely attachedto the axle, as shown. In its upper part is located a pulley, f, overwhich passes the chain g, the ends of which latter are attached to thelifting-lever and bowed bar c', as shown. i

The lifting-lever H is hinged to the standard, as shown, and is providedwith a springbolt, which engages with the rack-bar Iin the usualwell-known manner. The construction of this bolt, however, is peculiar.Its upper plate or face h extends over and incloses the rack-bar I, andthus prevents the bolt from becoming accidentally disengaged from therack-bar by the lateral movement of the lever. The lever also forms abrace of itself, whether it is moved or not.

The operation of these parts is not different from other machines ofthis class, and need not therefore be particularly described.

I do not broadly claim to have invented a spring-bolt, :nor to havecombined it with a rack-bar and lever; but,

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent ofthe UnitedStates, is-

1. The iron e, bent as described, in combination with the beams E, whenattached to the tongue at or near the evener, as described.

2. The spring-bolt h, constructed specifically as described-that is,withits covering-plate extending over and about the lever, for the doublepurpose of preventing the lever from moving laterally and for protectingthe internal'bolt mechanism, as described.

3. The combination of the standard F, rackbar I, lever H, and brace-rodt', the parts being arranged as described-that is, the rackbar beingsecured above to the standard and held below from vertical and lateralmovemeut by the brace-rod without other support, the. lever also beinghinged to the standard and secured to the rack-bar, as described.

This specification signed and witnessed this 9th day of August, 1870.

FRANCIS N. WELDEN.
